　　Jack loved playing sports. But on a day in August, it seemed that all sports were about to be taken away from him. Though injuries were nothing new for Jack, this one was much more serious. He would miss both the football and wrestling seasons. "I had to experience a long and painful recovery," said Jack.

　　Curtis Urbina, a famous coach, admired Jack's drive to keep going on the wrestling mat. After Jack got injured, he had an idea when sensing his sadness. He decided to bring Jack to practices to help him out.

　　Curtis Urbina asked Jack to watch how he and the other coaches worked with wrestlers. As expected, Jack wanted to take part in wrestling instead of being kept indoors all day. He offered to coach the toughest kids. He was a natural coach. He kept the kids interested and made it fun for them. He showed patience and persistence (坚韧不拔) needed to deal with those kids. "Making sure that they stayed in the room as required was the biggest part of my job," Jack said. "But I wanted to teach others some of the same lessons that wrestling had taught me."

　　One kid Jack coached was Stephen Singlak, aged 4. Stephen's parents were amazed when they watched Jack work with their son. "You can guess how Stephen felt at first as he was often wrestling with kids bigger than him," said Stephen's dad. "But Jack started going one-on-one with him. Jack would be on all fours, and Stephen was trying different moves. Stephen started liking wrestling instead of getting discouraged."

　　After struggling to win even one match early on, Stephen won about half of his matches in this season. "It was a great feeling when I knew I had played a part in Stephen getting to where he was," Jack said. "That coaching experience was just wonderful. I'm glad that I have a chance to help others. "
